Water Temperature Control Weir for Meramec Park Dam, Meramec River, Missouri: Hydraulic Model Investigation
Tests were conducted on a 1:40-scale model of the water temperature control weir for the Meramec Park Dam to investigate the discharge characteristics of the weir and determine its effectiveness in preventing the release of cold water from the hypolimnion. The model consisted of a section of the approach channel, the control weir, and the intake structure. Density stratification caused by temperature differentials in the prototype was simulated in the model by using saline and fresh waters. The weir was found to be effective for containing the cold water during release of desired rates of flow of 131 to 1028 cfs from the water supply and water-quality control (joint use) pool (el 608.0 to 675.0). Some withdrawal of cold water (approximately 7 percent) was observed with a discharge of 8000 cfs and a pool elevation of 680.0. The results of this study and similar tests on the Clarence Cannon and West Point water temperature control weirs were used to develop a preliminary, generalized technique for predicting the effectiveness of submerged weirs.
